in order to check IBANs, I want to calculate the modulo 97 of very large numbers. In my example the number is 700901001234567890131400. Two websites independently say, that the result of 700901001234567890131400 modulo 97 is 90 (e.g. https://www.entwicklertools.de/tools/mathematik-tools/modulo-rechner/). But when I calculate it with Alteryx the result is -79. What could be the reason for that? Is the first number to big for Alteryx to handle?
